FBO w/ Stock Turbo (is20.) On Arob's 13th revision.
Map 2 comparison of previous 2 part HPFP Test. Filled up tank with 93 and 2 gallons of E85, resulting in a rough mixture of e15 ish.
Test yields semi-similar results to map 3 test. Right around 4200 rpm fuel pressure dips to about 172 but car doesn't cut. Fuel pressure stays relatively consistent for rest of log. Will have to test map 3 on a lower ethanol content (93 octane) at a later time to 100% confirm ethanol is to much for pos HPFP
(SAFE TO CONCLUDE THAT HPFP CANT HANDLE MAP 3 WITH AN ETHANOL READING HIGHER THAN 10) |

FBO w/ Stock Turbo (is20.) On Arob's 13th revision.
Part 2 of HPFP Test.
Filled up tank with 93 and 2 gallons of E85, resulting in a rough mixture of e15 ish.
Test yields semi-inconsistent results, fuel pressure seems to be fine initially, it takes a small dip around 4200 rpm to 170 but car doesn't cut. Right around 4800 rpm it takes a bigger dip to around 140 and cuts. |

FBO w/ Stock Turbo (is20.) On Arob's 13th revision. Been a lot of offline testing, determined hpfp might be weak after lpfp was upgraded, SAI system was also deleted as valve was stuck open from carbon deposits. This is a general test to see if the car is able to handle map 3 right now. Also maps 1-3 are now flex enabled as the IE flex kit has been installed.
(STRONG HYPOTHESIS THAT HPFP CANT HOLD ANYTHING ABOVE E10, WILL CONTINUE TESTING)
